Lauren Jauregui, formerly of Fifth Harmony, makes a soulful statement on the new debut single “Expectations.” Joji, of Asian artist collective 88rising, paints a mood perfect for winter on “Attention” and his debut album. Indie rock group Beirut return after over three years with a new single that calls back to their earliest work, infused with a sense of place and history. And two more groups — boygenius, a collection of three indie artists working together, and Store Front, a new rock band — release songs in turn sweet and salty.
